3 Claims.

This application is a division of our application `Serial No. 14,506 ledMarch l2, 1948 (now Patent No; 2,533,359 dated December 12, 1950).

' This invention relates to machines for recording and reproducingdictation. Although the in- Lvention is especially useful with machinesof the `disk-record type, no unnecessary restriction thereto isintended.

Duringvthe course of recording dictation, the operator often finds needto listen back to por- 'tions of previously-recorded matter in order toreconstruct in his mind the run of his thoughts. In dictating machinesof `the usual type, the re- Border and reproducer are moved in unisonrelative to the rotating record, with one or the other being inoperative engagement with the record depending upon Whether recording orreproduc p Ting is desired. A movably mounted carriage is provided, andis movable manually to backspaoe the reproducer to the desired point onthe record. If after such backspacing the operator should not listen tothe end ci the recordation on the record, he will have to advance thecarriage manually to place the recorder a slight distance beyond itslast prior position of farthest advance, before @again resumingrecording, in order to assure that the recorder stylus will not engage arecorded area of the record and cause obliteration of matter alreadyrecorded. It is very useful in this respect to provide the operator withsome indication of the last prior position of farthest ad- Vance of therecorder, other than that to be `.gained visually by observing therelative positioning of the recorder stylus to the grooves on thegrecord, in order to facilitate thecorrect positioning of the recorderand also to permit a substan- Y tially full enclosure of thephonographic mechanism and record. The advantages of such fullyenclosure are several: notonly vdoes it protect the mechanism from dustand dirt, but it also enables the record to be kept free from dust YtoAn object of this invention is to lprovide a novel and improvedmechanism,V which is operated auto- `matically in thek `normal use ofthe dictating machine, to dene the position of farthest advance reachedby the recorder prior to a backspacing thereof, f.. l. Y a

2 Another object is to provide an improved dening mechanism which formsa position-indicating mark on the indexing card or slip of the dictatingmachine whenever the record-reproduce lever is shifted out of recordposition. Y

Another object is to provide a novelindicator.

in operative association with the defining mechanism, which indicator isadapted to cause the operator to position the recorder in advanceof therecordation by a suitable clearance margin.

These and other objects and features of the invention will be apparentfrom the following description and the appended claims.

In the` description of our invention reference is had to theaccompanying drawings, of which:

Figure 6 is a fractional vertical section taken substantially on theline 6--6 of Figure 2; and

Figure '7 is a partial view of the apparatus of Figure 6 as seen fromthe line 1,-1 of that ligure.

In the acompanying figures there is shown aV preferred embodiment of adictating machine incorporating our invention. This machine has ahousing I0 provided with a rectangular base I I. The housing has a frontwall I2 which slopes downwardly and forwardly and in which there is alarge opening I3 to expose a transverse section Ill ofthe frame of themachine (Figures 1 and 3).

' The housing has a 'portion arredo-ced height at its right end whichforms a horizontal platform i6 to permit access to the record as Willappear.

The frame of the machine comprises a horizontal top plate I'I havingpairs I8 and I9 of laterally-projecting bosses4 at its left andgrightsides respectively (Figure 2). The left pair 4of bosses is secured to anupstanding channeled frame member 2li by screws 2 I, and the right pairof bosses is secured to another upstanding journalled frame member 22 byscrews 23. These channeled frame members stand on the base of thehousing and rise to the height of theleft and right sides Vof themachine (Figures 1 and The topplate I'I has a bearing 24V in thecentralright-hand portion (Figure 3) in which there is journalled a dependingshaft of a turntable 25. Surrounding the right half portion of thisturntable is an arcuate flange 21 standing to a level just short of thetop face of the turntable. At the front and back of the turntable arestandards 28 and 29 on the top plate I1 (Figures 2 and 3). Mounted onthese standards is a channeled frame member 3l (Figures 2 and 3) whichoverlies the turntable and which carries a recordclamping mechanism 32fractionally indicated in Figure 2. Since this clamping mechanism formsno part of the present invention and is described in full in the pendingsole application of Charles W. Dann, one of the joint applicants of thepresent application, Serial No. 780,036, filed October l5, 1947, andentitled Phonograph, it is not necessary to be herein described otherthan that it has a handle 33 shown in Figure 1.

The righthand portion of the turntable overlies the platform I6 and isnormally covered by a shallow arcuate cover 33o which is hinged to thehousing and which is opened by the handle 33 whenever therecord-clamping mechanism is released. This part of the machine need notbe herein described since the 4same is the subject of a pending soleapplication of Richard M. Somers, one of the joint applicants of thepresent application, Serial No. 773,129, led September li), 1947, andentitled Closure for Phonograph."

The arcuate flange 21 extends around a portion of the turntable to theleft of the front standard 28, and then extends rectilinearly to theleft side of the top plate to form a. guide rail 32 for slidablysupporting the forward end of a carriage 35. further extension Illa ofthis rail along the left and rearward sides of the top plate constitutesa reenforcing flange. Supported between the standard 36 at the leftrearward corner of the top plate and the channeled frame member 3l is atransverse rod 31 on which the' carriage 35 isy slidably mounted, thecarriage having a long bearing 38 embracing this rod as shown in Figure2. At the forward end of the carriage there is a depending foot 39(Figures 2 and 3) which rests slidably on the guide rail 3ft. Thismount- Ving permits traveling movement of the carriage across the lefthalf portion of the turntable.

The carriage may be a casting having atop wall with a left side wall 40along its full length and with a right side Wall 4I along only itsrearward portion. In these side walls there are pivots 52 for pivotallysupporting a recorder 53 having a recording stylus 43a at its forwardend. Mounted at the front of the recorder on this carriage is areproducer le having a reproducing stylus 44a at its rearward end. Thisreproducer has a pair of cone pivots @6 at its forward end which engagea transverse rod 41 (Figure 2) carried by a vertical cylinder 41a. Thiscylinder is pivoted on two cone pivots 48 carried by a U- shapedstandard 49 mounted on the carriage 35. The reproducer is thus mounteduniversally for both vertical and transverse movement of its stylusrelative `to a mounted record R on the turntable.

The kdrive mechanism for the turntable and the carriage 35 comprises amotor (not shown) having a drive pulley 50 coupled directly to theturntable by a belt (not shown) which rides in a peripheral groove 52 ofthe turntable. Supported by the top plate is a laterally-extending feedscrew 53, fractionally shown in Figures 3 and 4, which is coupled by aspiral gearing 58 to a vertical shaft 51 that is journalled in the topplate.

flo

This vertical shaft is in turn coupled to the shaft 25 of the turntableby a gear train 55. Accordingly the feed screw is turned whenever theturntable is in rotation. Atthe back side of the i screw and in parallelrelation thereto is a stationary support rod 53, and at the fro-nt sideof the feed screw there is a similar support rod having end portionswith diametrically opposite ats '5i of which the left end portion seatsin a rectangular recess 52 provided in a depending standard 56 of thetop plate and the right end portion seats .in a rectangular recess 63provided in depending standard W: of the top plate as shown in Figures 25. (The transverse frame ber it has rearwardly-extending aperture.. 32engaging the rod BS, and has a lug 53 at its right end secured by ascrew I to the depending standard Sli as shown in Figures 2, 4 and 5.)These end portions are held in place to the standards by screws 33.These rods and 33 slidably mounted thereon a carriage 53 which movedalong the support rods by the feed ser 53 as is hereinafter described.This carriage se serves particularly as a traveling support i, arecord-reproduce lever i3@ of the for a certain indexing apparatus aswill appear.

The carriage 35 is coupled to the carriage @S by a mechanism comprisinga lever iii ich en braces the top plate l? and which pivoted thereto at68. This lever 61 has a short horizontal arm 33 above the top platecoupled by link 13 to the carriage 35 and has a relativ-elf.Y longhorizontal arm 1i below the top plate coupled by a link 12 to thecarriage 33, the l" lis being pivoted at their ends to the respec armsand carriages. These links have lenwhs proportional respectively to thedistance of the pivots on the lever 5? from the pivot cf the lever, andare so mounted to lie parallel to each other in all positions of thecarriages, so that the carriage 35 will be driven in a utecorrespondence with the traveling movement the carriage B6 but at a lessrate and through a smaller range.

The carriage E5 comprises a horizontal plate 13 having tworearwardly-extending fingers le and 15 displaced vertically from eachother to form a fork `which slidably embraces the rod 53. At the frontthe `plate 13 is bent upwardly and then rearwardly to provide anoverhanging top flange 16. Extending forwardly from the carriage areapertured lugs 11 and 1S which receive a sleeve 83 that is slidablymounted'on the cross rod Si). This sleeve has a collar Si at its leftend notched at 32. The left lug 11 of the carriage embraces this collarand an inwardly-projecting key 83 which engages this notch to lock thesleeve against turning relative to the carriage. The right lug 18embraces a reduced-diameter portion 815 of the rsleeve and is clampedthereto by a nut 85. Thus the carriage is secured rmly to the sleeve 8Uand is mounted for free back and forth traveling movement along thesupport rods 59 and bfi.

Mounted in the bottom plate 13 and top flange 1S of the carriage S6 is avertical pin 81 to the upper end 0I" which the link 12 is pivoted.Journalled on this pin 81 is a circular feed nut 33 which engagescontinuously the feed screw 53. Staked to the lower end of this feed nutis a gear 9| the forward portion of which projects through a slot 92 inthe front wall of the carriage 63 (Figure 4). Mounted on the plate 13 tothe right of this gear is a stud 33 on which there is pivoted a latchingpawl 94.

before referred to.

'.Also' pivotedon this stud isa rock4 lever-95 for operating thislpawl.The pawl is urged toiwards the gear 9| by'a tension spring 96 but fhasastop lug 91 which engages the back side of the rock lever 95 to preventengagement of 'f the pawl with the gear 9| unless the rock lever `is ina released position.

When the latching pawl is in engagement with the gear 9| the feed nut-89 is locked to the carriage 6G and the carriage is driven along therods 59 and Bil-whenever the turntable is rotated.

The sleeve 89 has a collar 99 intermediate itsends to provide alocalized bearing fora hub 99 of the record-reproduce leverhereinforwardly through the opening i3 in the housing |70 andconstitutes a means (1) for manually @moving the carriage G6 to positionthe recorder and reproducer in relation to a mounted record,

(2)V for controlling the recorder and reproducer in "relation to `amounted record, (3) for controllingthe locking of thefeed nut 89, (4)for operating a mechanism to effect a predetermined advance of therecorder and reproducer across the record when either is shifted fromneutral to effective condition, and (5) for op- A lera'ting an advancemarking mechanism. Of these several functions, the last will be hereinlater described in d etail Lsince it constitutes the essence of thepresent'invention.

The frame member |4 has an inset wall |9| along its,A lower portion, andabove which there 'is an opening- `H12 to the front of the rod |50.

' spline connection with the closure |95.

Secured as b-y welding to a top portion of the closure |06 is anupstanding U-member IIE bridged by a transverse rod l il. This rod isembraced slidably by a depending bifurcated arm ||2 of a slide H3, theslide being mounted on the left wall 4|) of the carriage 35 for frontand back movement by means of screws ||5 that thread into the left wallof the carriage and pass slidably through slots lid in the slide. j-Thebifurcated arm-H2 slides on the rod as the carriage 35 is moved, tomaintain con- Y tinuously a coupling of the record-reproduce lever withthe slide in all positions of the car-- riag'e.` -On the slide H3 is anupwardly-extending cam ||6 provided with a central dwell lita.

Extending leftwardly from the free end portions of the 'I recorder e3and reproducer i9 are respective lift fingers lil and H53 which overliethis cam. When the hand lever |99 is in a central or neutralposition-the position it ocl cupies in Figure 3--both lift fingers reston the dwell Hte to hold the recorder and reproducer' out of vcontactwith the record;- As they hand lever M39 is moved downwardly into arecord position, the slide H3 is moved forwardly to'move the cam H6ahead of the finger Hl and to allow the recorder stylus to engage therecordr under Vthe influence of a suitable downwardbiasing thereof, butthe other finger remains on vthe* dwell Ha to continue toholdthetreproducer stylus ina raised positionabove I'his control leverprojects 6 the record. pAsl the hand lever is `moved upwardly intoa'reproduce position, thecam H6 is rst moved under the finger I to raisethe recorder from the record and is then moved to the rear of theiingerV I8 to Iallow the reproducer to engage the record underthe'inluence of its downward biasing. i

Depending from the hub 99 of the hand lever |010 is a pin I i9 forcontrolling the rock lever 95. When the control lever is in vits neutralposition this pin engages a cam' |29 on the forward end portion of therock lever to hold the roclc lever in a clockwise position against thebiasing force of a tension spring |2I, in which position the latchingpawl VMis maintained out of engagement with the gear 9|. Thus, when thehand rlever |99 is in its neutral position, the feed nut 89 is unlockedto permit the carriages 59 and 35 to befmoved manually. However, whenthe hand lever |09 is in either recording or reproducing position, thepin ||9 isfre'e of the cam |20 and the latching pawl 9st 'is under theinfluence of its biasing spring to engage the gear 9| and lock thefeednut. Thus, in these effective positions of the hand lever, the carriage65 is coupled to the feed screw to cause the recorder` and reproducerlto ybe moved progressively across the record Ras the turntable isrotated. Pivoted to ,the rear endfportion of the roel: lever 95 is'apawl` |29. Thispawl is urged counterclockwise, as it appears `in FigureLl, by a tension spring `|2l.to a position defined by the engagement ofa stop lug |25 of the pawl against therock lever.` Since this pawl |23is farther removed fromthe pivot Vcenter @than is the toothof thelatching pawl 94, it has a greater range of movement and will'engage thegear 9| sooner when the 'rock lever .is released and will jon ,anotherwith consequent .obliteration of the be disengaged sooner from the gear9| `when the rock lever is actuated than will the latching pawl 913.`Moreover, since Vthe tooth of the pawl E23 is oiset considerably to theleft of a line drawn from its pivot.l axis |22 to the pivot axis 93 andis positioned ahead of the pivot axis |22 as with respect to the axis93, the initial movement of the rock lever after the pawl engages thegear 9| is effective to produce a delinite counterclcckwise movement ofthe gear before the latching pawl engages this gear. The amount of thismovement will vary depending upon whether the pawl |23 will rst engage atooth or a space between two successive teeth of the gear Si, but in anyca-se the gear will be turned mere or less in relation to the latchingpawl so that thisl pawl will engage aspace between two successive teethof the gear and willp-ositively lock the feed nut. This counterclockwiseturning of the gear 9i, which. occurs incidental to placing the recorderor reproducer into effective condition, effects an .advance o f the.recorder and reproducer across the record. This advance is produced so'that if an operator turnsthe hand lever |95 to neutralv position andthen restores it to recording position, the recording stylus will be ata clearance distance ahead of the recordation on the record to preventsuperposing of one recordation ,recorded matter.

- A detentfi-s-provided on the right end of the closure Ille to definethe neutralgfrecording vand reproducing positions of the hand lever me.This detent comprises a rearwardly-extending arm |25 riveted to theright end |533 of the closure Iili and carrying a roler |21 at itsrearward end. This roller engages a serrated edge |26 provided on alever |29 that is pivoted at |39 to the standard $4 aforementioned, thelever |29 'oe-- ing urged constantly against the roller by a tensionspring |3I. The serrated edge |28 has three notches defining therespective positions of the hand lever abovementioned.

Clamped between the lug 18 and nut 85 is. a forwardly-extending arm |t|which has a notch |42 engaged by a portion of the bottom plate 13 of thecarriage 65 to hold the arm in fixed relation to this carriage. Securedby screws |63 to the forward end f this arm is an upstanding member Uitlwhich extends through an opening M in the frame member Hl, this openingbeing to the front of the inset Wall lil! and extending along the lengthof the path of traveling movement of the carriage 55. The member Ifificarries a punch and die assembly |45 by means of which annotations aremade on. an index slip I-l carried lby a holder |48 that ovel'lies theopening M at a distance above the inset wall ll (Figures 3 and 6). Theholder is of a common form comprising a flat plate IGS having top andbottom edges folded back on itself to provide a channel through whichthe index slip |511 can be inserted.

The punch and die assembly |46 comprises a U-shaped extension |5 of themember IM, which extension embraces the index slip |41 and holder Il.The legs of this U-shaped extension lying below and above the holder |48have side plates |53 and I5@ secured thereto. Formed between thisextension and the lower side plate |53 is a pair of rectangularapertures |5541 and lnea and formed between the extension and the upperside plate |54 is another pair of aligned rectangular apertures |55 and|56. In the holder iii-S there is a pair of clearance slots |51 and |53between these aligned pairs of apertures. Mounted in the upper aperturesare respective push-operable punches |59 and |60 `which are urgedupwardly by suitable springs (not shown). As the punches are presseddownwardly they pass through the clearance slots |51 and |58 and enterthe respective apertures |55a and Ia to punch small rectangular openingsin the index slip. Since these punches are carried by the carriage @tand moved along the index slip in accordance with the traveling movementof the recorder and reproducer translating devices relative to therecord, one punch may serve to indicate lengths of separate items ofdictation and the other to indicate places whereat errors and/orcorrections are made.

The advance marking mechanism hereinbefore mentioned is carried with thepunch assembly ifijust described, and comprises a U-bracket |2 having asupporting arm IGI fastened at Iila. 'to the lower leg of the U-member|59 and the punch assembly (see Figure 3). This bracket |52 ispositioned within the opening |45 below the slip holder |118 and isapertured to form two spa-ced bearings for slidably supporting'animpaling pin |63. The upper end of this pin is pointed co that when thepin is driven upwardly it will pierce a small hole |13 in the index slipH11, there being a clearance slot Iit for the impaling pin in the slipholder |48 along the length of the latter. This impaling pin iscontrolled by the hand lever I so that the holes |18 are pierced in theindex slip |41 atpoints whereat the machine is taken out of .recordingcondition. When the operator backspaces the carriage to listen to aportion of dictation already recorded, the hole |13 farthest along theindex slip serves as an indication of the position of farthest advanceto which the recording operation has proceeded, this being in accordancebroadly with the teachings of the Somers Patent No. 2,251,173 issuedJuly 29, 1941. The way in which the pin |63 is operated to punch theholes |18 is herein next described.

Normally, the pin |53 is held by a spring |65 that is located betweenthe upper leg of the U-member I B2 and a collar |83a on the pin, in anunoperated position dened by the abutment of the collar against thebottom leg of the U-member. Pivoted at |61 to the left side of the armi521 is a rock lever |58 having a forwardly-extending arm |6661. bentover 'at right angles thereto and terminating below the impaling pin,the rock lever being held in a neutral position by a tension spring |59connected between it and a pin on the arm |41. On the forward endportion of the arm |5130. there is a hardened piece i for impingementagainst the bottom end of the impaling pin as the lever |68 is rockedcounterclockwise, as it appears in Figure 3. The pin is so actuated topunch the index slip whenever the hand lever |110 is moved fromrecording position to neutral position by a mechanism consisting of anarm |12 secured to the hub 99 of the hand lever and a roller |13 on therearward end of the rock lever It. When the hand lever is moved torecording position an inclined cam |12a on the end of the arm |12engages the roller |13 and cams the rock lever I in a reverse-i. e.,clockwise-direction until the roller rides oi' the upper edge of the camthrough a slot |14 (Figure 2), the cam |12@r then having the positionrelative to the roller shown by dash-dot lines in Figure When the handlever it@ is next returned to neutral position, the under side of thecam |12@ engages the roller |13 and cams the rock .lever in a forwarddirection to move the impaling pin upwardly to punch a hole |18 in theindex slip, the roller |13 then moving on the under side oi the cam andreturning to the relationthereto shown by their full-line positions inFigure 2.

A feature of our invention lies in the provision of a novel die andindicating member |15 in association with the advance-marking meansdescribed in the foregoing paragraph. This member |15 is riveted to theupper leg of the U-member 15s of the punch assembly (Figure 3) andextends forwardly therefrom across the index slip. The forward endportion |16 of this member |15 is bent back on itself in spaced parallelrelation thereto and across the back side of the member in respect ofits direction of advance across the index slip. The end of this curvedend portion serves as an indicating pointer |11. rlhe central opening ofthis curved end portion 15 is aligned with the impaling pin |63 so thatthe end portion |15 serves to back the border of the slip around the pinas the slip is punched. After the machine is taken out of recordingcondition, and the carriage 65 is moved manually for any purpose and isthen to be restored to a suitable position to resume recording, theoperator is to set the carriage to that position whereat the pointer 11is aligned with the hole |18 which was produced when the machine waslast taken out of recording condition. Since the pointer |11 is at ashort distance back from the impaling farthest along the index slip willcause the,l

recorder stylus to be positioned a slight distance Y ahead of the lastrecorded groove convolution to prevent possible overlapping of the finaland initial portions of successive recordations on the record. i

Instead of punching or impaling the slip to make position-indicating orother annotating marks thereon, we may alternatively make suitableimpressions in a, slip within the scope of our invention, and it isintended. in the claims that the term punch shall include, asequivalents. means for so making impression marks on the slip. In theclaims the recorder 43 and reproducer lift are referred to generally bythe term "translating means.

The embodiment of our invention herein particularly shown and describedis illustrative and not necessarily limitative of our invention sincethe same is subject to changes and modifications without departure fromthe scope of our invention, which we endeavor to express according tolthe following claims.
